380/95 = 4 doublings
start 33500 i double 67000
2 double 134000
3 double 268000
4 double 536000
33500 (2^4)=536000

cosine = adjacent / hypotenuse
cosine(72) = adjacent/hypotenuse
hypotenuse = adjacent/ (cos 72) = 6/cos72 = 19.42
then pH = -log[H3o+]
CORRECTION .....I misread the question (I thought it was angle of ascension)....asinus probably has it correct
Tangent 12 = opp/245
opp = tan12 * 245 = 52.076
54 +6 - 52.076 = 7.924 ft tall (asinus calc a little off)
I think it is nCr 12 C 3 = 220
You have nPr 12 P 3 = 1320
I am not real strong in this topic though.....

8x/6 = 72/64 There are easier ways to solve this, but the question asks to use common denominator ( 192)
8x/6 * 32/32 = 72/64 * 3/3
256x / 192 = 216 / 192 equate the numerators
256x = 216
x = 216/256 = 27/32 = 0.84375
Just substitue in the values you are given...
231 cm = 62 \(\sqrt[3]{t}\)+76
(231-76)/(62) = \(\sqrt[3]{t }\)
15.63 years = t
use the arcsin function (also known as sin-1 or asin )
On web2.0 calc press the '2nd' key then the asin key then the value then =
|5-12| + 16 =
|-7| + 16
7 +16 = 23
I believe the domain of this fxn is all n such that 5/n is not equal to 5/0 (undefined)
-infinity < 0 < +infinity but NOT zero
